Abstract
Abstract A splinter warhead for guiding flying bodies for combating aerial targets by detonation by a proximity fuse upon close approach to the target includes front and rear body portions interconnected by a warhead envelope constructed as a splinter warhead transporting structural member carrying an explosive charge detonatable by the proximity fuse. The explosive charge, which has an essentially circular cross section, has a lining of pre-formed splinters on its peripheral surface, this lining being disposed between the explosive charge and the warhead envelope. The pre-formed splinters have essentially a ball or spherical shape and an individual weight of less than 1 g. The average diameter of the explosive charge is more than 25 times the average diameter of the splinters. The splinters may be arranged in a single layer or in more than one layer, and may be all of the same diameter, or the splinters may be of different diameters and be arranged in groups with each group comprising splinters of the same diameter.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
193 words
In a guided flying body for combating aerial targets, and of the type including front and rear body portions interconnected by a warhead envelope constructed as a splinter warhead transporting structural member carrying an explosive charge detonatable by a proximity fuse upon approach of the flying body to a target: the improvement in which said warhead comprises, in combination, a circular cross section explosive charge; a warhead envelope surrounding said charge; and a lining of pre-formed splinters on the circumferential periphery of said explosive charge and within said warhead envelope; said splinters having essentially a ball shape and an individual weight of less than 1 g; the average value of the diameter of said explosive charge being in excess of 25 times the average value of the diameter of said splinters; the circumferential peripheral surface of said explosive charge being outwardly concave and defined by an arcuate generatrix; the rear portion of said outward concave surface being a substnatial distance radially outwardly of the front portion of said outwardly concave surface, whereby, upon detonation of said explosive charge, a cone-shaped splinter ray is directed forwardly of the direction of movement of said body.

Claim 3
Dependent Claim
19 words
A splinter warhead, as claimed in claim 1, in which said splinters are arranged in plural radially adjacent layers.
Claim 4
Dependent Claim
29 words
A splinter warhead, as claimed in claim 1, in which the splinter rays, upon detonation of said charge, are directed in a narrow and imaginary circle surrounding said warhead.
Claim 5
Dependent Claim
14 words
A splinter warhead, as claimed in claim 1, in which said splinters have facets.
Claim 6
Dependent Claim
20 words
A splinter warhead, as claimed in claim 1, in which said splinters are hollow and are filled with active substances.
Claim 7
Dependent Claim
15 words
A splinter warhead, as claimed in claim 1, including inert material filling the splinter interspaces.
Claim 8
Dependent Claim
15 words
A splinter warhead, as claimed in claim 1, including explosive material filling the splinter interspaces.
Claim 9
Dependent Claim
30 words
A splinter warhead, as claimed in claim 1, in which said warhead envelope comprises a very stable material having, as compared to said splinters, a smaller mass per unit area.
Claim 10
Dependent Claim
43 words
A splinter warhead, as claimed in claim 1, in which said explosive charge has its forward end, which is pointed toward the target, formed with an outwardly facing conical hollow space coaxial with said explosive charge, said hollow space having a metal lining.
Claim 11
Dependent Claim
38 words
A splinter warhead, as claimed in claim 1, in which the circumferential peripheral surface of said explosive charge is defined by an arcuate generatrix comprising two intersecting circular arcs whose respective centers are spaced substantially from each other.
